SEE PROFILE

We experimentally demonstrate a Raman fiber laser based on multiple point-action fiber Bragg grating reflectors and distributed feedback via Rayleigh scattering in an ~22-km-long optical fiber. Twenty-two lasing lines with spacing of ∼100 GHz (close to International Telecommunication Union grid) in the C band are generated at the watt level. In contrast to the normal cavity with competition between laser lines, the random distributed feedback cavity exhibits highly stable multiwavelength generation with a power-equalized uniform distribution, which is almost independent on power. © 2011 Optical Society of America OCIS codes: 190.5650, 140.3550, 290.5870. Multiwavelength fiber lasers have attracted great interest owing to their wide applications in wavelength-division-multiplexing (WDM) systems, instrument testing, optical fiber sensors, and spectroscopy. Several techniques have been proposed to ensure stable multiwavelength laser operation based on semiconductor optical amplifiers [1], erbium-doped fiber lasers [2], spectrum sliced super
